This paper presents an adaptive cable equalizer employing a time-domain approach called the phase detection technique in 0.13 mu m CMOS technology. The equalizer can compensate a 24-inch microstrip on an FR4 PCB, which has an 18dB channel loss at 5GHz. Meanwhile it also avoids offset-sensitive rectifiers which normally exist in conventional equalizers. The proposed adaptive cable equalizer consumes 39mW excluding the output buffer from a 1.5-V supply voltage and the measured BER is less than 10(-13).

This paper presents a simplified overshoot control technique suitable for equalization of NRZ data pattern. Compared to conventional design, the generation of overshoot reference voltage is greatly simplified by using a top holder with swing-dependent built-in offset. Fabricated in a 65nm CMOS technology, the adaptive equalizer is capable of running at 13.5Gb/s over a 20-inch FR4 trace with a loss of 20.5dB at 6.75GHz while consuming 17mW from a 1.2V supply.

This paper presents a burst-mode equalizer for the communication incorporating electrical idle state which is usually used for power management. Fabricated in 0.18 mu m CMOS technology, the proposed equalizer can compensate over 90-inch microstrip on an FR4 PCB, which has a 40dB loss at 3GHz. The proposed overshoot control scheme with reference calibration can reduce offset-induced error on detections and is observed to achieve jitter improvement of 0.06UI. With the help of envelope detector and digital adaptation, the reaction time under burst-mode transmission is 5.5ns or 33bit-time. The equalizer consumes 26.7mW from a 1.8V supply and measured BER is less than 10(-12).

This work proposes an adaptive equalizer employing a new overshoot control for achieving optimized equalization. The proposed overshoot detection scheme obviates the need for slicers to achieve high-speed operation with low power dissipation. The circuit adapts to FR4 trace lengths for up to 40 inches. The measurement results show that the equalizer achieves a good eye performance while consuming 40mW from a 1.8V supply.
